However, getting satisfactory results may be more complicated. Hallucinations, inaccurate information, contradictory answers, invalid parsed data, or incomplete responses. In this session, you’ll move your RAG knowledge to the next level using LangChain4j and Docling. ## Speakers ### [Alex Soto](https://www.wearedevelopers.com/@alex-soto) Director of Developer Experience at Red Hat ### [Markus Eisele](https://www.wearedevelopers.com/@markus-eisele) Cloud Native and AI in a hybrid world.
